          WHEREAS, the Company desires to obtain additional
capital for use in connection with its business through the issue
and sale of certain obligations, and Purchaser is willing to
purchase such obligations of the Company, on the terms and
conditions set forth herein.

          NOW, THEREFORE, in mutual consideration of the premises
and the respective representations, warranties, covenants and
agreements contained herein, the parties agree as follows:

per annum, payable quarterly by automatic debit on the first day

   ARTICLE II - REPRESENTATIONS AND WARRANTIES OF THE COMPANY

          The Company hereby represents and warrants to Purchaser
as follows:

               Section 2.1  Corporate Status.

               (a)  The Company is a corporation duly organized,
validly existing and in good standing under the laws of the
Commonwealth of Pennsylvania and has the corporate power to own
and operate its properties, to carry on its business as now
conducted and to enter into and to perform its obligations under
this Agreement, the Debentures, the Preferred Stock Purchase
Agreement, the Warrant, the Registration Rights Agreement, the
Subordination Agreement between First Union National Bank, the
Company, and Purchaser, and any other document executed and
delivered by Purchaser in connection herewith or therewith
(collectively, the "Operative Documents").  The Company is
qualified to do business and is in good standing in each state or
other jurisdiction in which such qualification is necessary under
applicable provisions of law, except where the failure to so
qualify would not have a material adverse effect on the financial
condition or results of operations of the Company.  The states or
other jurisdictions in which the Company is so qualified are set
forth on Schedule 2.1(a) hereto.  A certified charter of the
Company and a good standing certificate for each state in which
it is qualified to do business are attached to Schedule 2.1(a).

               (b)  Schedule 2.1(b) sets forth a complete list of
each corporation, partnership, joint venture, limited liability
company or other business organization in which the Company owns,
directly or indirectly, any capital stock or other equity
interest (the "Subsidiary" or, collectively, the "Subsidiaries"),
or with respect to which the Company or any Subsidiary, alone or
in combination with others, is in a control position, which list
shows the jurisdiction of incorporation or other organization and
the percentage of stock or other equity interest of each
Subsidiary owned by the Company.  Each Subsidiary is duly
organized, validly existing and in good standing under the laws
of the jurisdiction of incorporation or other organization as
indicated on Schedule 2.1(b), each has all requisite power and
authority and holds all material licenses, permits and other
required authorizations from government authorities necessary to
own its properties and assets and to conduct its business as it
is now being conducted, and is qualified to do business as a
foreign corporation (or business organization) and is in good
standing in every jurisdiction in which such qualification is
necessary under applicable provisions of law, except where the
failure to so qualify would not have a material adverse effect on
the financial condition or results of operations of the Company. 
All of the outstanding shares of capital stock, or other equity
interest, of each Subsidiary owned, directly or indirectly, by
the Company have been validly issued, are fully paid and
nonassessable, and are owned by the Company free and clear of all
liens, charges, security interests or encumbrances.  A certified
charter for each Subsidiary and good standing certificates for
each of the states in which each Subsidiary is qualified to do
business are attached to Schedule 2.1(b).

               (c)  Schedule 2.1(c) sets forth a complete list of
"affiliates," as that term is defined in Rule 405 of Regulation C
adopted under the Securities Act of 1933, as amended (the
"Securities Act"), with a brief statement describing the basis of
each affiliation.

          Section 2.2  Capitalization.

               (a)  The authorized capital stock of the Company
consists of (i) 10,000,000 shares of common stock, par value
$.10 per share (the "Common Stock"), of which 2,962,784 shares
are issued and outstanding, and (ii) 1,000,000 shares of
undesignated preferred stock, with rights and preferences fixed
by the Board of Directors in accordance with the corporate laws
of the Commonwealth of Pennsylvania and the Company's Articles 
of Incorporation, none of which are outstanding.  All shares of
Common Stock outstanding have been validly issued and are fully
paid and nonassessable. There are no statutory or contractual
pre-emptive rights, rights of first refusal, antidilution rights
or any similar rights held by any party with respect to the
issuance of the Debentures.  The offer, sale and issuance of the
Debentures do not require registration under the Securities Act
or any applicable state securities laws.

               (b)  The Company has not granted, or agreed to
grant or issue, any options, warrants or rights to purchase or
acquire from the Company any shares of capital stock of the
Company, and there are no contracts, commitments, agreements,
understandings, arrangements or restrictions as to which the
Company is a party, or by which it is bound, relating to any
shares of capital stock or other securities of the Company,
whether or not outstanding except for (i) the Debentures to be
issued pursuant to this Agreement, (ii) 314,164 shares of Common
Stock reserved for issuance pursuant to the Company's 1988 Stock
Option Plan, for which options to purchase 99,010 shares are
outstanding, (iii) a warrant to acquire 100,000 shares of Common
Stock held by Chase Manhattan Capital Corporation, and (iv) the
obligation to issue to Osprey Partners, in certain circumstances,
a warrant to purchase 125,000 shares of Common Stock. 
Schedule 2.2 sets forth a summary of such options, warrants and
other rights to acquire capital stock of the Company.

          Section 2.3  Authorization.

          The Company has full legal right, power and authority
to enter into and perform its obligations under this Agreement
and any of the other Operative Documents, without the consent or
approval of any other person, firm, governmental agency or other
legal entity.  The execution and delivery of this Agreement, the
issuance of the Debentures hereunder, the execution and delivery
of each other document in connection herewith or therewith to
which the Company is a party, and the performance by the Company
of its obligations hereunder and/or thereunder are within the
corporate powers of the Company and have been duly authorized by
all necessary corporate action properly taken, and have received
all necessary governmental approvals, if any were required.  The
consummation of the transactions contemplated by this Agreement
and the fulfillment of the terms hereof  do not and will not
contravene or conflict with the Articles of Incorporation or
Bylaws of the Company or any material agreement to which the
Company or any of its Subsidiaries is now a party or by which any
of them or their properties is bound, or constitute a default
thereunder; or results in the creation or imposition of any lien,
charge, security interest, or encumbrance of any nature upon any
of the property or assets of the Company or any of its
Subsidiaries pursuant to the terms of any such agreement or
instrument; or violates any provision of law or any applicable
judgment, ordinance, regulation or order of any court or
governmental agency.  The officer(s) executing this Agreement,
the Debentures and any other document executed and delivered by
Purchaser in connection herewith or therewith, is duly authorized
to act on behalf of the Company.

          Section 2.4  Validity and Binding Effect.

          Each of the Operative Documents is the legal, valid and
binding obligation of the Company, enforceable against the
Company in accordance with its terms, except as enforcement may
be limited by bankruptcy, insolvency or other matters affecting
the rights of creditors generally and general principles of
equity.

          Section 2.5  Other Transactions.

          Except as disclosed on Schedule 2.5, there are no
outstanding loans, liens, pledges, security interests, agreements
or other financings upon which the Company or any Subsidiary is
obligated or by which the Company is bound.  Consummation of the
transactions hereby contemplated and the performance of the
obligations of the Company under and by virtue of the Operative
Documents will not result in any breach of, or constitute a
default under, any material mortgage, security deed or agreement,
deed of trust, lease, bank loan or credit agreement, or any
corporate articles, certificate or bylaws, agreement or
certificate of limited partnership, partnership agreement,
limited liability company agreement, license, franchise or any
other material instrument or agreement to which the Company is a
party or by which the Company or its properties may be bound or,
to the knowledge of the Company, affected or to which the Company
has not obtained an effective waiver.

          Section 2.6  Litigation.

          Except as set forth on Schedule 2.6, there is no
litigation, arbitration, claim, proceeding or investigation
pending or threatened in writing which the Company or any
Subsidiary is a party or to which any of its respective
properties or assets is the subject which, if determined
adversely to the Company or such Subsidiary, would individually
or in the aggregate have a material adverse effect on the
financial position, results of operations or business of the
Company and its Subsidiaries, taken as a whole.

          Section 2.7  Financial Statements.

          The consolidated financial statements of the Company
and its Subsidiaries for the fiscal years ended February 25,
1994, February 24, 1995, and February 23, 1996, and the unaudited
consolidated financial statements as of the nine (9) months ended
November 29, 1996, which the Company previously has delivered to
Purchaser, fairly present the financial condition of the Company
and its Subsidiaries, as at the respective dates of and for the
periods referred to in such financial statements and have been
prepared in accordance with generally accepted accounting
principles ("GAAP") consistently followed throughout the periods
involved.  The consolidated balance sheets and the related notes
fairly present the financial condition of the Company and its
consolidated Subsidiaries as of the respective dates thereof, and
the consolidated statements of income, cash flows and changes in
stockholders' equity and the related notes fairly present the
results of operations of the Company and its consolidated
Subsidiaries for the respective periods indicated.  There has
been no material adverse change in the financial condition of the
Company and its Subsidiaries taken as a whole since November 29,
1996.

          Section 2.8  SEC Reports.

          The Company's Common Stock is listed on the American
Stock Exchange and has been duly registered with the Securities
and Exchange Commission ("SEC") under the Securities Exchange Act
of 1934, as amended (the "Exchange Act").  Since February 26,
1993, the Company has filed all reports, registrations, proxy or
information statements and all other documents, together with any
amendments required to be made thereto, required to be filed with
the SEC under the Securities Act and the Exchange Act
(collectively, the "SEC Reports").  All SEC Reports since
February 26, 1995, have been timely filed.  The Company
previously has furnished to Purchaser true copies of all the SEC
Reports, together with all exhibits thereto that Purchaser has
requested.  As of their respective dates, the SEC Reports
complied (or will comply, as the case may be) in all material
respects with all rules and regulations promulgated by the SEC
and did not (or will not, as the case may be) contain any untrue
statement of a material fact or omit to state a material fact
required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which
they were made, not misleading.

          Section 2.9  Absence of Changes.

          Since November 29, 1996, (i) neither the Company nor
any of its Subsidiaries have incurred any liabilities or
obligations, direct or contingent, or entered into any
transactions, not in the ordinary course business, that are
material to the Company, (ii) neither the Company nor any of its
Subsidiaries have purchased any of its outstanding capital stock
or declared, paid or otherwise made any dividend or distribution
of any kind on its capital stock, (iii) there has not been any
change in the capital stock, long-term debt or short-term debt of
the Company, and (iv) there has not been any material adverse
change, or any development involving a prospective material
adverse change, in or affecting the condition (financial or
otherwise), results of operations, business or prospects of the
Company or any Subsidiary, taken as a whole.

          Section 2.10  No Defaults.

          Except as set forth on Schedule 2.10 and except where a
default or event of default does not and would not constitute a
Material Adverse Event, no default or event of default by the
Company or any Subsidiary exists under this Agreement or any of
the other Operative Documents, or under any other instrument or
agreement to which the Company or any Subsidiary is a party or by
which the Company or any Subsidiary or its respective properties
may be bound or, to the knowledge of the Company, affected, and
no event has occurred and is continuing that with notice or the
passage of time or both would constitute a default or event of
default thereunder.

          Section 2.11  Compliance With Law.

          To the Company's knowledge, the Company and any
Subsidiary are in compliance with all laws, regulations, decrees
and orders applicable to them (including but not limited to the
Foreign Corrupt Practices Act, laws, regulations, decrees and
orders relating to environmental, occupational and health
standards and controls, antitrust, monopoly, restraint of trade
or unfair competition) to the extent that noncompliance, in the
aggregate, cannot reasonably be expected to cause a Material
Adverse Event.

          Section 2.12  Taxes.

          Except as set forth on Schedule 2.12, the Company and
its Subsidiaries have filed or caused to be filed all federal,
state and local income, excise and franchise tax returns required
to be filed (except for returns that have been appropriately
extended), and has paid, or provided for the payment of, all
taxes shown to be due and payable on said returns and all other
taxes, impositions, assessments, fees or other charges imposed on
it by any governmental authority, agency or instrumentality,
prior to any delinquency with respect thereto (other than taxes,
impositions, assessments, fees and charges currently being
contested in good faith by appropriate proceedings, for which
appropriate amounts have been reserved), and the Company does not
know of any proposed assessment for additional taxes or any basis
therefor.  No tax liens have been filed against the Company or
any of its properties.  The Company's federal income tax
liability has been finally determined by the Internal Revenue
Service and satisfied for all taxable years up to and including
the taxable year ended February 24, 1995, or closed by applicable
statutes of limitation.

          Section 2.13  Certain Transactions.

          Except as set forth on Schedule 2.13(i) and except as
to indebtedness incurred in the ordinary course of business and
approved by the Board of Directors of the Company, neither the
Company nor any Subsidiary is indebted, directly or indirectly,
to any of its officers or directors, or to their respective
spouses or children, in excess of an aggregate amount of $60,000,
and none of the officers or directors or any members of their
immediate families are indebted to the Company or any Subsidiary
in excess of an aggregate amount of $60,000 or have any direct or
indirect ownership interest in any firm or corporation with which

Company has a business relationship, or any firm or corporation
which competes with the Company or any Subsidiary, except that
officers and/or directors of the Company may own no more than
4.9% of the outstanding stock of any publicly traded company
which competes directly with the Company.  Except as set forth on
Schedule 2.13(ii), no officer or director of the Company or any

          The Company  and each Subsidiary has good and
marketable title to all of real and material personal property
owned by it, free and clear of all liens, security interests,
pledges, encumbrances, equities claims and restrictions of every
kind and nature whatsoever, except as disclosed on Schedule 2.14
and except for such liens, security interests, pledges,
encumbrances, equities claims and restrictions which are not in
the aggregate material to the business, operations or financial

Any real property and buildings held under lease by the Company
or any Subsidiary are held under valid existing and enforceable
leases, except as disclosed on Schedule 2.14 or which are not
material and do not interfere with the use to be made of such
buildings or property by the Company.

          Except as set forth in Schedule 2.15, the Company is
the lawful owner or has a valid right to use the proprietary

and its Subsidiaries on the date of this Agreement.

aside on its books, reserves deemed by it to be adequate with
respect thereto.

and local laws, regulations and ordinances, and such laws,
regulations and ordinances of foreign jurisdictions, governing
such business operations and the use and ownership of such

issued pursuant to this Agreement shall bear a legend in
substantially the following form:

          THIS DEBENTURE HAS NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT") OR ANY
APPLICABLE STATE SECURITIES LAW AND MAY NOT BE TRANSFERRED UNLESS
(i) THERE IS AN EFFECTIVE REGISTRATION STATEMENT UNDER THE

any Debenture, by acceptance thereof, agrees, prior to any
transfer of such Debenture, to give written notice to the Company
of such holder's intention to effect such transfer or conversion

notice of intended transfer shall be accompanied by, if
applicable, a copy of the opinion of counsel to such holder
reasonably satisfactory to the Company, to the effect that
registration under the Securities Act of such Debenture, in
connection with such proposed transfer, is not required.  If in
the opinion of such counsel, the proposed transfer of such
Debenture, may be effected without registration of such
Debenture, under the Securities Act, such holder shall be
entitled to transfer such Debenture in accordance with the terms
of the notice delivered by such holder to the Company.  The
Company will promptly upon such transfer deliver new Debentures
not bearing a legend of the character set forth in Section 8.1,
unless in the opinion of such counsel subsequent disposition by
such holder may require registration under the Securities Act. 
If the proposed transfer of such Debenture may not be affected
without registration of such Debenture under the Securities Act,
the holder thereof shall not be entitled to transfer such
Debenture in the absence of an effective registration statement.

          ARTICLE IX - AMENDMENTS, WAIVERS AND CONSENTS

holders of at least 50% in aggregate principal amount of
outstanding Debentures; provided that without the written consent
of the holders of all of the Debentures then outstanding, no such
waiver, modification, alteration or amendment shall be effective
(a) which will change the time of payment of the principal of or
the interest on any Debenture or reduce the principal amount
thereof or change the rate of interest thereon, (b) which will
change any of the provisions with respect to optional
prepayments, or (c) which will change the percentage of holders

      ARTICLE X - INTERPRETATION OF AGREEMENT; DEFINITIONS

          Section 10.1  Definitions.  Unless the context
otherwise requires, the terms hereinafter set forth when sued
herein shall have the following meanings and the following
definitions shall be equally applicable to both the singular and
plural forms of any of the terms herein defined:

          "Affiliate" shall mean any Person (other than a
Restricted Subsidiary) (a) which directly or indirectly through
one or more intermediaries controls, or is controlled by, or is
under common control with, the Company, (b) which beneficially
owns or holds 5% or more of any class of the Voting Stock of the
Company or (c) 5% or more of the Voting Stock (or in the case of
a Person which is not a corporation, 5% or more of the equity
interest) of which is beneficially owned or held by the Company
or a Subsidiary.  The term "control" means possession, directly
or indirectly, of the power to  direct or cause the direction of
the management and policies of a Person, whether through the
ownership of Voting Stock, by contract or otherwise.

          "Business Day" shall mean any day other than a
Saturday, Sunday, or other day on which banks in Tennessee are
authorized to close.

          "Default" shall mean any event or condition, the
occurrence of which would, with the lapse of time or the giving
of notice, or both, constitute an Event of Default as defined in
Section 7.1.

          "ERISA" shall mean the Employee Retirement Income
Security Act of 1974, as amended and any successor statute of
similar import, together with the regulations thereunder, in each
case as in effect from time to time.  References to sections of
ERISA shall be construed to also refer any successor sections.

          "Event of Default" shall have the meaning set forth in
Section 7.1 hereof.

          "Guaranties" by any Person shall mean all obligations
(other than endorsements in the ordinary course of business of
negotiable instruments for deposit or collection) of such Person
guaranteeing, or in effect guaranteeing, any Indebtedness,
dividend or other obligation of any other Person (the "primary
obligor") in any manner, whether directly or indirectly,
including, without limitation, all obligations incurred through
an agreement, contingent or otherwise, by such Person:  (a) to
purchase such Indebtedness or obligation or any property or
assets constituting security therefor, (b) to advance or supply
funds (i) for the purchase or payment of such Indebtedness or
obligation, (ii) to maintain working capital or other balance

the primary obligor to make payment of the Indebtedness or
obligation, or (d) otherwise to assure the owner of the
Indebtedness or obligation of the primary obligor against loss in
respect thereof.  For the purposes of all computations made under
this Agreement, a Guaranty in respect of any Indebtedness for
borrowed money shall be deemed to be Indebtedness equal to the

has been guaranteed, and a Guaranty in respect of any other

Indebtedness equal to the maximum aggregate amount of such
obligation, liability or dividend.
